The following benchmark concurs with the idea that "Assign" is faster than "Push" for this example.
use Benchmark qw(:all) ;
my $count = 1000;
my $foobar = 'foobar' x 1000;
timethese($count, {
'Assigned' => sub { my @assigned = $foobar =~ /(foo)/g;},
'Pushed' => sub { my @pushed; push @pushed, $1 while $foobar =~ /(
+foo)/g; },
});
Benchmark Results:
Benchmark: timing 1000 iterations of Assigned, Pushed...
Assigned: 1 wallclock secs ( 0.80 usr + 0.00 sys = 0.80 CPU) @ 12
+50.00/s (n=1000)
Pushed: 1 wallclock secs ( 0.93 usr + 0.00 sys = 0.93 CPU) @ 10
+75.27/s (n=1000)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
